Mundorf also have two other caps at a higher cost. Do you think these are worth the extra money or are we just splitting hairs at this point? I think they are called gold/silver and gold/silver/oil. Their costs are $120 & $160 respectively.

Andre,

Splitting hairs, maybe, maybe not. It would totally depend on what is upstream from the tweeter, amp, source, media. Its a fine line between getting the most detail, and then going to far only to find there isn't enough media worth listening to.

Then, with that said, if you don't have a very well treated room, any more spent on caps would be a total waste of money You won't be able to hear the difference anyway. Just my opinion.

I replaced mine last week with mundorf's silver / oil. The value of the cap on my ERR'S are 3.9 uf . I also repaced the resistors with mundorf's audiophile grade resistors. Although I have not had much time to sit and listen, what I heard was even more smoooth. For me the cost of the upgrade was $ 220.00 and was worth it. Keep in mind that great care needs to be taken during installation as these caps are about twice the pysical size as the clarity caps.

I found that after switching to the mundorf caps & resistors my ERR's sound slightly smoother initially but they never sounded worse than the clarity caps. I have about 70 hours on my ERR'S and 25 of those hours on the new resistors and caps. It's nice to know their is room for improvment!

Hi,I have recently purchased a used ERR speaker and like it very much except for a certain recessed, sound that makes instruments and voices sound kind of "hollow". I also have the feeling that the treble sounds grainy. It seems like there is a problem with the frequency balance that I cannot solve by playing around with the different resistors. The low value resistors sound too bright in my room and the 15 Ohm ones sound too dead, but non of them really solves the problem of the recessed midrange and hollow sounding voices and instruments

Speakers and system are in a non acoustically treated living room. Due to WAF the speakers are positioned very close to the back walls in a corner where all the system and the TV is located. I realise this may not be optimal, but I can't change it…

Could a capacitor / resistor upgrade solve this? You mention the Mundorf in this thread, but I have read very positive reviews of the following:

Hi again,

Rereading my previous post I just realised that I may have given a too negative impression about the ERR sound. It is an amazing speaker that images like no other speaker I have heard before. The bass extension is really surprising for such a small enclosure. The ERR really sounds almost like a "big" full range speaker. The issue about the slightly grainy treble is really due to a desire on my side to make it "perfect". Previously I had a monitor, which obviously was far from full range, but the highs were a little purer and cleaner, that's why I posted my previous message. I am still not sure if this is due to the omnidirectionality of the tweeter which causes that wounderful soundstage but also more reflections from side and rear walls. Perhaps it is a matter of getting used to it.

On the other side, another thing worth mentioning is that for now I am driving the speakers with a solid state amplifier, which does not seem to be the "ideal" for this speaker. I am planning to introduce a tube amp soon. Perhaps that alone improves the quality of the highs enough to make me forget about capacitor upgrades... :)

Hey decwalex,

I upgraded the caps to Mundorf supreme 3.9 and the sound REALLY blossomed. You must get the speakers away from the wall tho even if you have to listen at low volume and move them after the session.After consulting with Steve I've got my ERR's just inside a pair of french doors(that slide into wall thankfully so they do not to disturb acoustics) toe'd in slightly and now have have sound flowing through 2 continuous rooms. The listening room is treated and sounds glorious but my bedroom to the rear of the speakers sounds awesome as well with a different yet also fantastic sound. On my tube amp the Torii III treble adjustments took the most of my energy when making adjustments so that could be tricky. Thankfully with the Torii's treble pots its easy to tune to taste. Good luck,JD

Hi JD,

Thank you very much for your suggestions. Mundorf Caps seem to be a common recommendation on this forum to upgrade the ERR sound.

What is exactly achieved by increasing or decreasing the value of the Cap? If I have understood correctly other threads about this topic here, a higher cap value widens the frequency range that is directed to the tweeter (making it reach lower frequencies). Is that right?

PD: Your sliding doors set up to make it possible to use the speakers in two different rooms is really impressive! What a good idea! I wish I could do something similar at home!
